Every DeepSeek Harness plugin

What it is — This plugin registers four faithful palettes from Solarized and Selenized into the DeepSeek Harness Web theme runtime.

Who it is for — If you are using DeepSeek Harness Web and like Solarized or Selenized color schemes, this plugin is suitable for you. If you only use DeepSeek Harness in a command-line environment, you do not need this plugin.

Watch out — The sandbox test passed: it was successfully installed in a new profile and registered with Harness. No obvious issues found.

The verdict — I would install it provided that I am using DeepSeek Harness Web.

What it is — dsh-pet is a desktop pet plugin supporting sprite animation, agent state linkage, drag, and reminder tools.

Who it is for — If you use the DeepSeek Harness agent for complex tasks and need visual cues to stay focused, dsh-pet's state linkage suits you. Users who complete work only via command line or text interface do not need it because they require no extra reminders.

Watch out — Tested successfully in a clean profile where it registers with harness. No obvious issues found; the settings panel supports adjusting size, position, and skin preview.

The verdict — I would install it because it provides visual feedback during agent thinking, but only if your workflow needs timed reminders or state cues.

What it is — dsh-vision-bridge allows text-only models to see images in the input box.

Who it is for — If you are using DeepSeek V4 for text conversations needing image processing, dsh-vision-bridge suits you. If you are using a vision-native model or avoid image content, you do not need this plugin.

Watch out — The install command succeeds. No obvious issues found. Configuration requires an OpenAI-compatible multimodal model, such as qwen-vl-max.

The verdict — I would install it because it enables text models to see images in conversations, but sandbox testing shows it loads as ordinary dependency without extending the profile layer, so use it per the README.

What it is — Tool for backing up and restoring DeepSeek Harness user data with scheduled auto-backup and GitHub sync.

Who it is for — Users who need to back up and sync DeepSeek Harness user data across macOS, Linux, and Windows to a private GitHub repository. Users who do not have tar in their PATH are not suitable because the tool requires it.

Watch out — Sandbox testing passed and it can be registered in a new profile. Installation from source requires manually approving the build script. Backups contain plaintext credentials, so do not sync to untrusted locations.

The verdict — I would install it because it provides path-traversal rejection during restore and GitHub sync support, but only if using a private repository.

What it is — It is the host-side Typert remote for dsh-tool-writing.

Who it is for — People using the DSH writing panel and relying on dsh-tool-writing engine are suitable. If you use only client-side running writing tools, you don't need this plugin.

Watch out — Sandbox test passed, successfully registered in fresh profile. Requires dsh-tool-writing@0.3.0 dependency. No obvious issues found.

The verdict — I wouldn't install it because it only exposes read data and write operations remain on the host side engine.

What it is — Client-side writing panel and full-book index view for DeepSeek Harness, shown only in writing-preset sessions, covering project volumes, stats, corpus library, full-text search, and evolution graph.

Who it is for — Users performing long-form novel writing with the writing preset benefit from this plugin for sidebar panel and index view support. Users not engaged in novel writing or evolution tracking can skip this plugin.

Watch out — Tested successfully in a fresh profile where it registers with Harness. Requires host-side installation of related writing services. No obvious issues found.

The verdict — I would install it because it enhances writing workflow with data management and search, but only if host-side writing tools are already set up.

What it is — KnowLP-RAG plugin provides dual knowledge-graph RAG for Markdown notes with P/S-Agent traversal and weight feedback loop.

Who it is for — When using DeepSeek Harness to process large Markdown notes that require retrieval with dependency chains and similarity alternatives, this plugin is suitable to install. Users who only need simple vector or full-text search with small note volume need not install it.

Watch out — After install, set KNOWLP_VAULT and KNOWLP_GRAPH_DIR environment variables manually. Sandbox test passed in fresh profile with registration, no obvious issues found.

The verdict — I would not install it because it requires Python environment bootstrapping and is only useful in specific note scenarios.

What it is — Removes the folder selection requirement before starting a conversation in the DeepSeek Harness Web interface.

Who it is for — When conducting conversations in DeepSeek Harness Web, the goal is to avoid manually selecting a workspace. Users who are accustomed to manually selecting workspaces can handle the folder choice through alternative approaches.

Watch out — Sandbox test passed with successful installation and registration into profile. No obvious issues found. The static check indicates execution of shell commands.

The verdict — I would install it because it handles zero-workspace startup by automatically creating the default directory and opening the input box, but only if the default directory suits my daily workflow.

What it is — dsh-opencode-go-usage plugin displays OpenCode Go subscription usage in the DeepSeek Harness composer dock with rolling/weekly/monthly windows and reset countdowns, including a built-in credential editor.

Who it is for — If you use OpenCode Go models in web interface management and need to monitor subscription remaining time and countdowns, this plugin fits.

Users not using OpenCode Go don't need to install it for this purpose.

Watch out — Sandbox test passed: installed in new profile and registered by harness. Static check shows it executes shell commands. Requires OpenCode Go session cookie treated like password. No obvious pitfalls found; from source install, manual build script approval needed if build blocked.

The verdict — I wouldn't install it because it only monitors OpenCode Go usage and requires a full session cookie, which may not justify the effort unless you frequently need web-based stats.

What it is — dsh-s1 provides first-class s1_* tools for web research in DeepSeek Harness.

Who it is for — When using DeepSeek Harness for web research, this plugin can provide s1_* tool support. For users not running in a profile environment, it cannot be used.

Watch out — Sandbox test passed in a new profile. It requires S1_KEY to function. No obvious issues found.

The verdict — I would install it because it runs in-process with a bundled s1 skill.

What it is — Uses a vision sidecar to describe image attachments, enabling image paste on text-only DeepSeek models.

Who it is for — Use it when running official text-only models in the web UI and pasting screenshots to query red text. Users who prefer native vision models don't need this plugin.

Watch out — Sandbox test shows pnpm blocks the build script for github:shinjiyu/dsh-plugin-multimodal, requiring manual allowance for registration. Tests found no other obvious issues.

The verdict — I would install it because it enables image paste on text-only models but requires manual build approval.

What it is — Optimize raw instruction into professional four-section prompt (Role / Task / Context / Format) via Harness llm service, with composer button and auto-optimize hook.

Who it is for — When building complex agents requiring structured prompts using DeepSeek Harness, this plugin provides the prompt_optimize tool and ctx.promptOptimizer service. Users who prefer raw input formats can utilize its composer button and hook for optimization options.

Watch out — Sandbox test passed: installed in new profile and registered by harness. No obvious pits found. Supports configurable options like default temperature 0.2 and maxTokens 1200.

The verdict — I would install it if the agent needs structured prompts because it provides tools and services to reduce manual optimization work, assuming integration with DeepSeek Harness.

What it is — Adds support for the nono sandbox backend.

Who it is for — If you need to use the nono sandbox backend to execute tasks in DeepSeek Harness, install this plugin. Windows users do not need to install this plugin because they lack native binding support.

Watch out — Real test shows it can be installed but the build script github:omdsh-dev/sandbox-nono is blocked by pnpm, preventing harness from completing registration. Users need to manually allow that build to install properly. No other obvious issues found.

The verdict — If I were you I would go for installing it since it enables the distinct sandbox-nono row via profile overlay for nono backend use, yet from source install one must manually permit the build script.

What it is — Integrates microsandbox microVM backend support

Who it is for — When needing microsandbox_exec or microsandbox_fs tools in the DeepSeek Harness, this plugin can be used. Users on macOS Apple Silicon do not need to install it because macOS Apple Silicon real-host acceptance is not included in the first release.

Watch out — Installation from source requires manually allowing its build script. Tests show this step is required for registration completion. No other obvious issues found.

The verdict — I would install it if needing microsandbox_exec or microsandbox_fs tools, because it provides fail-closed microVM capability, but from source install requires manually allowing its build script.

What it is — JSON Schema validation plugin offering pure functions for data validation, path localization, schema explanation, and default application.

Who it is for — Agent needs to validate JSON data for API responses or plugin manifests. Developers with built-in verification can opt for alternative methods.

Watch out — Sandbox test passed with successful registration in a new profile. No obvious issues detected.

The verdict — I would install it as it provides an independent pure function verification kernel for reliable schema validation.

What it is — Provides regex tool to DeepSeek Harness for testing, extraction, replacement and static explanation.

Who it is for — When using a model in DeepSeek Harness to verify user-provided regex patterns, extract fields from text logs and perform safe replacements, this plugin applies. It is not necessary if the model primarily handles structured data analysis.

Watch out — Sandbox testing passed: installed in a fresh profile and registered in the profile. No obvious issues found.

The verdict — I would install it because its static parsing capability provides direct value in model pattern verification scenarios.

What it is — DSH plugin registers JSON query tool supporting JMESPath subset path queries.

Who it is for — When DSH Agent processes JSON data, if structural path query is needed, this plugin is suitable. If you only need string-level search, this plugin is not needed.

Watch out — Sandbox test passed, installed in fresh profile and registered into harness. No obvious issues found.

The verdict — I would install it because it provides read-only JSON querying capability.

What it is — DSH plugin providing base64/url/hex encoding, hash and UUID generation.

Who it is for — Suitable for Agent scenarios handling encoding and hashing in DeepSeek Harness. Users in monorepo integration may find it unsuitable as an independent bundle.

Watch out — Sandbox test passed: installed in new profile and registered by harness. Will execute shell commands but not a defect. No obvious issues found.

The verdict — I will install it because it is zero-dependency pure functions and passed sandbox test.

What it is — Add a simplified auto-chess game to the DSH sidebar, supporting human vs AI or AI vs AI.

Who it is for — If you want to experience AI-assisted strategy games in the DSH web sidebar, such as playing chess against AI or watching AI battles. Users who prefer standalone local game software don't need this plugin.

Watch out — Sandbox test shows installation is possible but the build script is blocked by pnpm, requiring manual approval for the build to complete registration. Users need to manually allow the build script to install successfully. No other obvious issues found.

The verdict — I would install it because it offers a unique browser-based AI strategy simulation, but must manually allow the build script during source installation.

What it is — DSH plugin providing local image OCR and understanding via macOS Vision.

Who it is for — Developers working on macOS who need to process image inputs with OCR or scene description using DeepSeek Harness should install this plugin. Users not running macOS 11+ can skip this plugin.

Watch out — Sandbox testing passed in a fresh profile with successful registration. First run requires compilation taking about 5 to 10 seconds then caching. Requires macOS 11+ and Xcode Command Line Tools.

The verdict — I would install it because it provides fully local image understanding on macOS, but only if running on macOS 11+ with Xcode Command Line Tools.

What it is — dsh-honcho-sync is a bridge plugin connecting DeepSeek Harness (DSH) to Honcho memory service. After installation, DSH automatically syncs every conversation turn to a self-hosted Honcho service and provides the AI with tools for recall, search, and remember across sessions.

Who it is for — If you are developing an agent in a DSH profile that requires persistent memory across sessions and have already deployed a Honcho service, this plugin can automatically sync conversations and inject context.

Users who do not need cross-session persistent memory and rely only on information within the current session do not need to install it.

Watch out — A self-hosted Honcho service must be deployed first (one Docker command). Sandbox testing passed: installed in a fresh profile and registered into the profile by harness. Configuration is done graphically through DSH settings panel without editing YAML.

The verdict — I would install it because it adds cross-session memory tools to DSH, but only if I can deploy Honcho myself; not worth it for tasks that only require a single session.

What it is — Integrates DeepSeek Harness with local Obsidian vault using obsidian_* tools to support note search, read, write, move, and trash.

Who it is for — When DeepSeek Harness agent needs local note handling, this plugin fits. If only cloud-based knowledge operations are needed, not suitable for this plugin.

Watch out — Passed sandbox test after installing in a new profile and being registered by harness. No issues found in static checks.

The verdict — I would install it because it allows direct local vault access without servers.

What it is — Adds a QR-code button above the Settings button in the DeepSeek Harness sidebar footer, enabling phones to connect to the web UI via an auth-gated reverse proxy.

Who it is for — If you need to scan a QR code with your phone to connect to the DeepSeek Harness web UI on local network or internet, this is suitable. If you primarily use the desktop browser for DeepSeek Harness without needing phone cross-device access, this plugin may not fit your scenario.

Watch out — Successfully tested by installing on a new profile and registering into the profile with Harness. Static check indicates it will execute shell commands. No other obvious issues found.

The verdict — I would install it because it simplifies phone access in specific network settings, but the premise is trusting the network and using short session lengths.
